You probably know this already, but the ground is made up of multiple layers. The surface layer, topsoil, is rich in organic material. You probably want to dig a bit deeper, or find a patch of eroded soil, to get some dirt that doesn't start out with nearly as much organic impurities.
Yes, digging down until the soil is lighter than the top is good, just mineral soil, almost no organic junk, a good place to pick up too is on river beds, the water already do the work on washing it up.
Even better, just go down to a beach to gather your dirt there and- oh. The point is to extract the silicon dioxide from regular, dirty, topsoil. Filtering off the organic material is part of the journey.
@@MGSLurmey eh, dirt in general have a lot of non organic contaminants, like metal oxides, who are tricky to remove from the silicon dioxide, but in a way, the organic junk add a bit of fun for the extraction (and beach sand has contaminants too)
Analytical grade dirt 😂 You are funny. And brave! I wouldn't dare to touch grass, especially without PSE! 😮 Nice video 👌 Edit: Fun fact: That's pretty much what NIST Standards are. Standard products, but maximally homogeneous and tested a huge number of times for statistical use for analytical labs, to compare results to see how accurate they are.

awesome video! just a few useful tips: it will be easeier to melt the hydroxide first and then add the raw SiO2, then also its quite bad for the glass frit to filter the silicate-silicon dioxide-hydroxide mix because there is some hydroxide left so i'd use a buchner instead.
@MarianLuca-rz5kk just an silly joke that scientist didn't have contact with nature. In my opinion, be far to nature is what make people sick and out of natural resources of healing that the body have...
there is a way to avoid the sodium hydroxide step, which involves either crushing the sand to a very fine powder, or finding very fine sand. the particle size simply needs to be smaller than the crystal size of the minerals in the rock that the sand came from, this means that every individual mineral is exposed, and can be reacted with. and the only thing that will remain is the silicon dioxide grains, which are already silicon dioxide, which means no sodium hydroxide necessary.
@Amateur.Chemistry thank you for the thanks at the end of the video :) I'm looking forward to your next videos, especially the spicy ones ;) the first one was great... Alfred N would be proud of you :)

4:44 Ahh, the poor mans reflux condenser! Love it. And use it too, despite working in a professional lab with lots of different reflux condensers. But time is money 👌
You can make water glass or silica gel - there are many 'recipes' in various chemistry textbooks (e.g. Armarego, Brauer, Vogel). It's relatively easy to make and much cheaper than professional chromatographic silica gels from chem suppliers. Various types of aluminas are also worth of exploring.
Pleas keep on doing such simple experiments. You use stuff that i can actually replicate and many other ! Pleas keep finding cool recepies to do with regular-ish compunds !
Great Video. I also would like to see, what we can get out of the first HCl-wash. For sure, there are Elements like Iron and some more inside. The next step we need, is to produce our own HCl and H2S04 from the stuff, we find in nature. 🙂
You'll find it in modded Factorio :P Even fairly hardcore minecraft modpacks, like GTNH, still rely a lot on magical electrolysers and the like which give you pure products for magic. Though with GTNH, fewer and fewer of those remain with each update, replaced with more realistic processes. I'm actually working on a game where separating things is a major part of any refining and you're always working with complex materials rather than pure molecules/elements; I'm sure there's around 100 players in the world who are really going to enjoy that ("Pyanodon's mods are _way_ too simplified!") :D
I will also mention that if you simply make some piranha solution, it will do pretty much every step for you all at the same time, except for removing the iron impurities. there may also be titanium and feldspar impurities.
If I had access to a furnaceand was doing the same project, I think I would have put the dirt in a furnace first, maybe with an oxidizer to burn off the organic material. Would that have made any of the next steps easier or require less caustic chemicals for cleaning?
6:19 I thought silicon can't form double bonds? Can this exist because there is a constant equilibrium where the double bond is between the 3 oxygens? curious.
It really avoids forming double bonds, which is where we get the wild variety of silicate minerals. Quartz does not have double bonds - each silicon atom is actually covalently bonded to _four_ oxygen atoms (but each of them is shared with another silicon atom). But molecular silicon dioxide does exist. And it indeed has two double bonds, and it is linear just like carbon dioxide. Of course, that's not what was produced here; that would be your typical SiO4 (4+). But I don't think it's all that wrong to draw molecular silicon dioxide - it does _form_ , it's just that it polymerises very easily for obvious reasons. The double bond rule is not a rule; more like a... guideline. You'll find there are many molecules where silicon forms double bonds, and they aren't _unstable_ , really - they just polymerise easily and lose those double bonds.
It'll mostly get alkaline and group two metals, like calcium, sodium and potassium, and maybe a bit of transition ones like iron... But unless he get it to a specialized analyzer, we would see just a mess of combined metals, hydroxides and oxides.
Some hot piranha solution would have removed all the organic bits prior to the conversion to silicate. Your sand would have been almost snow-white and have none of those black bits.
I did the sodium silicate reaction in water and it seemed to work fine, just took a while, I did contaminate the solution with (i think) chromium ions after I couldn't find glass filters and tried to use stainless steel wool to filter off undissolved debris (like bugs) after I realised why my filter paper kept self destructing
Sooo, you should have used some water, as a flux, to get the reaction going in the can. What you where left with was still sodium hydroxide and silicon dioxide . What dissolved was the sodium hydroxide, and when you added sulfuric acid you made sodium sulfate. The solution already being saturated, it came out of solution immediately. And at no point later did you add enough water to dissolve more than ~50g of sodium sulfate. So if there was 66g before you added 150ml water, there would still be 16g sodium sulfate undissolved in the solution. Just think about it, granular sand has about 160g/100ml, but after the "reaction" you still had almost 200ml of sand, where is the product coming from? If you stir all your product in a 500ml beaker of water, how much remains undissolved?
Could you sum the energy inputs needed to convert clean "sand" (not dirt, such as a nice mineable deposit) into silicon dioxide, in optimal conditions? Include the energy production of the reagents. Then, the energy needed to convert SiO2 into metalloid silicon - for use in building solar cells. I suspect a solar cell will never return more energy than was needed to produce it.
Heh. I have plenty of sand in my yard with little organic matter- but in the Space Coast of Florida, most of the sand is just weathered coral and thus mostly calcium carbonate. I'd have to go a few hundred miles to find actual silicate sand.
Depending on the crystaline structure silicon dioxide dust can be very damaging to breath. The amorphous structure is not terrible, but fully crystaline silica dust is very hazardous.
I don't know much about chemistry, but wouldn't adding hydrogen peroxide in the hydrochloric acid wash step help? Shouldn't it burn some of the carbon, so that you don't have to filter so much?
It's funny, because it's a part that's entirely ignored in pretty much all games that include chemistry - you always have magical centrifuges and electrolysers that effortlessly separate stuff out. How do you get aluminium from clay? Just run it through an electrolyser! Nicely separated 100% pure batches of all the individual atoms. Real-life chemists would kill for magic machines like that :D How does electrolysing clay even work? Well... shut up, that's how! :D
Silicon dioxide is mentioned in genesis 2, along with gold, and aromatic plants. "The gold of that land is good, there is onyx and aromatic plants there also" It's like they wanted us to build computers.
...i was thinking, you could have burned off the majority of the organic materials and washed the remaining salts away with water. The acid wash at this point would ne optional, but probably not necessary unless there was some really wierd contamination.
TBH I never thought of dirt being a mix of sand and other stuff, it just always seemed like its own thing. To see the result after cleaning it looks like the sand I see at the lake shore beach in my city
awesome video! would it be possible to make a video about extracting the pure clay minerals, like kaolin and serpentinite, or at least removing the metallic impurities from a good quality reddish clay? Apparently oxalic or citric acid is good at dissolving metal impurities from clay. I've wanted to know if this was possible, so I could make my own crucibles without having to order in a bunch of stuff. the big thing i worry about if you were to try and refine clay minerals is that i feel like they're more delicate than just normal silicon dioxide, and using acid and heat might damage them and weaken them somehow. A well made kaolinite ceramic crucible with pure silicon dioxide as grog can withstand the temperature at which pure iron or platinum would melt. And crucibles for that sort of work are a pain to get.
Thanks! I could make a video about extracting some minerals form clay, and making some elemental aluminum but as of now I have a ton of other thing planned, but maybe in the future I will find some time :)
